  • Applications

    Octanoyl salicylic acid (CAS 70424-62-3) is used as a lipophilic emollient and solvent in cosmetics and personal care, aiding fragrance solubility and formulation stability in creams, lotions, and perfumes. In perfumery, it can serve as a fragrance ingredient and carrier, helping to dissolve and deliver aroma compounds. In coatings, inks, and adhesives it may act as a processing aid or solvent to improve film formation and gloss. In polymers and plastics it can function as a plasticizer or processing aid to enhance flexibility and processability. As an industrial intermediate, it is employed as a building block for ester derivatives used in fragrance chemistry and pharmaceutical synthesis, with use governed by local regulations and formulation limits.
